Location of events unknown / unclear.
The sled dogs of explorer Sir Ernest Shackleton are led out by a group of men - each holding one dog on lead.
They pass sign advertising Spratt's Dog Cakes - including product endorsement claiming that the dogs would be fed on the cakes during the Antarctic Expedition.
Pan across dogs standing in front of signs. Pan across dogs in their kennels, they bark and wag their tails; etc. Probably from 1914 when Shackleton set out on trip across Antarctic.
